Jennifer Lopez and Steven Tyler will join Randy Jackson as “American Idol” judges next season, after months of turnover and speculation about the future of TV’s top-rated show.

With pomp and special effects, Fox finally assembled the new pieces of the “Idol” panel that will be returned to its original three-member format for its 10th season. Actress-singer-dancer Lopez and Aerosmith frontman Tyler will have the job of trying to match the chemistry of former judges Simon Cowell and Paula Abdul.

Translation: One has to be mean and the other has to act like they came straight from the bar.

Ryan Seacrest made the announcement Wednesday in front of several thousand people, after the new judges joined him on stage at the Forum arena in Inglewood, where the final national auditions for next season’s singing contest were held.

Tyler said he wanted to join the show because “it’s being a part of something much bigger than yourself. I want to bring some rock to this rollercoaster and show if you’ve got the heart, the talent, the feeling to do this, you could be the next American Idol.”

“I’m so excited,” said Lopez, reportedly paid $12 million to join the show. “I’m looking for the next Michael Jackson.”

One must wonder if she knows she may be the next Abdul.

Cowell said in January that he was leaving to launch a new talent show for Fox in 2011. Judges Ellen DeGeneres and Kara DioGuardi exited the show this summer. Abdul left in 2009 over a contract dispute.

THEY WON’T ALWAYS HAVE PARIS: Paris Hilton canceled her Asia tour and returned home when she was denied entry at Tokyo’s airport Wednesday following a drug violation in the United States.

“I’m going back home, and I look forward to coming back to Japan in the future,” a smiling Hilton told reporters before departing on her private jet.

The 29-year-old celebrity socialite arrived at Narita International Airport, outside the Japanese capital, two days after pleading guilty to a misdemeanor drug charge in Las Vegas. Japan has strict immigration laws that bar entry to those convicted of drug offenses, although exceptions are occasionally granted.

Hilton was to appear Wednesday at a news conference in Tokyo to promote her fashion and fragrance lines. She arrived Tuesday evening, but was stopped at the airport and spent the night at an airport hotel after being questioned by officials. Hilton also canceled planned appearances in Malaysia and Indonesia, where they also don’t like convicted drug offenders.

Kazuo Kashihara, an immigration official at Narita International Airport, said if Hilton had applied for an entry permit farther ahead of her arrival, there might have been a chance for Japan’s justice minister to consider an exception in her case. “She just showed up the day after (pleading guilty),” he said.

PUTTING THE FAN BACK IN FANATIC: A Madonna fan was arrested outside her New York home for the second time in four days after he was reportedly found carrying two pocket knives as he professed his love for her.

Robert Linhart, a 59-year-old retired firefighter, was taken into custody Tuesday after the singer’s security guards spotted him outside the Manhattan property. His SUV was parked nearby, propping up large posters declaring his feelings for Madonna.

One sign read, “Madonna, I need you,” while on another, he wrote: “Tell me yes or no. If it’s yes, my dream will come true. If it’s no, I will go. XXX.”

Think you know Disneyland? Well, ponder this: There are people who go there every single day. Seriously. Every day. And about a zillion others who shelled out hundreds for annual passes. What do they know that can make your visit more enjoyable?
